RE: [APD] Wave maker -- or - Keeping Current on The Flow of Ideas

["S. Hieber" <shieber at yahoo_com>]

I do not disagree.

A great alternative to the wavemakers that work by
switching the electrical current on/off is the relatively
new device branded as "SCWD." This device switches the
water current between two outlets. It can run on a single
pump (and accepts a wide varitety of flow rates). I've had
one running for several months without a hitch.

One use for device like this is to get circulation in a
large tank with a smaller pump than might otherwise be
necessary -- basically, the pump only needs to circulate
water in half the tank at a time. the switching cycle is
rapid enough that the off period is inconsequential.
